Update the Monitoring Storage Nodes

You must reconfigure HPE Ezmeral Data Fabric Monitoring when you add additional OpenTSDB or Elasticsearch nodes, or when you change the OpenTSDB or Elasticsearch node locations.

1. Run configure.sh on each node in the HPE Ezmeral Data Fabric cluster with the -R, -ES, and -OT parameters. Optionally, you can include the -ESDB parameter.

   /opt/mapr/server/configure.sh -R -ES <comma-separate list of Elasticsearch nodes> \
    -OT <comma-separate list of OpenTSDB nodes> [-ESDB <filepath>]

   For the entire list of available configure.sh parameters, see configure.sh

   If you encounter any errors after running configure.sh, see Troubleshoot Monitoring Installation Errors
2. If you updated the list of Elasticsearch nodes, restart the all the Fluentd, Elasticsearch, and Kibana services.

   maprcli node services -name fluentd -nodes <space separated list of Fluentd nodes> -action restart
   

   maprcli node services -name elasticsearch -nodes <space separated list of Elasticsearch nodes> -action restart
   

   maprcli node services -name kibana -nodes <space separated list of Kibana nodes> -action restart
   

3. If you updated the list of OpenTSDB nodes, restart the collectd, OpenTSDB, and Grafana services.

   maprcli node services -name opentsdb -nodes <space separated list of OpenTSDB nodes> -action restart
   

   maprcli node services -name collectd -nodes <space separated list of collectd nodes> -action restart
   

   maprcli node services -name grafana -nodes <space separated list of Grafana nodes> -action restart
